2 Claims.

The invention relates to improvements in shoes and methods of making thesame, the primary object of the invention being the provision of animproved water-tight shoe construction which is highly efiicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts andthe methods of pro cedure hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which Fig. 1 is aside view of a shoe, with portions broken away, embodying the invention,the sectional portion thereof being taken substantially on line 1,1 ofFig. 2; v

Fig. 2 an enlarged transverse section of a shoe taken substantially online 2-2 of Fig. 1; and

Fig. 3 a horizontal section taken substantially on line 3-3 of Fig. 1.

In carrying on the method of construction, a suitable insole 5 isprovided on its bottom with a coating of suitable sealing material suchas latex compound. Then a suitable shoe upper 6 has its edges turnedunder the edges of said insole and secured thereto around the heel andtoe portions by means of tacks 8 and at other portions by means ofstaples 9. Then a second coating of the sealing material is applied overthe entire bottom, including the inturned edges of the upper and therebyproviding a layer or coating 6' which, with the layer or coatingoriginally applied, completely embraces the inturned edges of the shoeupper, as best shown in Fig. 2.

After this has been done a filler 10 of cork, felt or the like isinserted against the bottom of the insole 5 and between the inturnededges of the upper, and a middle sole 11 is then secured to the insole 5by means of stitches 12 passing through the inturned edges of the upper,as best shown in Fig. 2. All of these steps are preferably taken whilethe sealing coating 6' is still fluid or plastic so that a complete andperfect seal is provided for the inturned edges of the shoe upper,including the openings necessarily formed by the tacks, staples andstitches employed. An outer sole 13 is then secured to the middle sole11 by means of stitches ,14 extending around the edges of the two, .asindicated. The contacting parts of all other seams oi. the shoe upperare firmly cemented before stitching with an adhesive rubber compoundwhich seals the same against entry of moisture.

By means of the construction and methods set forth, a shoe is providedhaving all scams or joints therein completely sealed and protectedagainst theentry of moisture. In this manner, a waterproof shoe isprovided which is capable of economical manufacture and highly eflicientin use.

While the preferred form of construction and method of procedureforcarrying the invention into effect have been illustrated anddescribed, these are capable of variation and modification withoutdeparting from the spirit of the invention. It is therefore not desiredto limit the patent to the precise details set forth but to includetherein also such variations and modifications as fall within the scopeof the appended claims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. The method of making shoes which consists in applying a coating offluid sealing material to the underside of an insole; turning the edgesof an upper under the edges'of said insole while said sealing materialis still fluid; applying. a

coating of sealing material to the underside of said -insole and to theunderturned edges of said upper, while said first coat isstill fluid, V

thereby forming a waterproof coating bifurcated at the edges to embracesaid underturned edges; and securing an outer sole to said insole andupper.

2. The method of making shoes which consists in applying a coating offluid sealing material to the underside of an insole; turning the edgesof an upper under and mechanically securing them to the edges of saidinsole while said 0
